Android Auto allows users to enhance their driving experience with applications from the Google Play Store and through sideloading. To enable sideloading, users must access developer settings in Android Auto by navigating to the Apps section, tapping on version and permission info multiple times, and activating the Unknown sources toggle. Users can then install the Android Auto Apps Downloader (AAAD) from its GitHub repository, which helps discover and install third-party applications.
Notable applications include CarStream, which allows access to YouTube content while parked, although it is not compatible with Android 15 or later. Screen2Auto enables users to mirror their entire Android phone screen onto the infotainment display, allowing access to any application, including YouTube. AABrowser provides a full web browsing experience on Android Auto, supporting touchscreen controls and a keyboard for input, but should only be used when safely parked.
